Last week, thousands of children in Toronto learned an important lesson about the seriousness of plagiarism, from the head of the largest school board in Canada.

Plagiarism is when you copy someone else’s work and claim the ideas or writing as your own.

When you use someone else’s writing in a school report, for instance, you must let the reader know where the passage came from.

That’s known as “citing the source” or “giving attribution.”
